Solidago plant named ‘Dansosolo’

ABSTRACT

A new and distinct Solidago plant named ‘Dansosolo’ characterized by having small flowers; rapid growth rate and growth cycle; and flowers that are primarily arranged on the top trimester of the stem.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of goldenrodplant, botanically known as Solidago L. and hereinafter referred to bythe cultivar name ‘Dansosolo’.

Goldenrods are members of the sunflower family (Asteraceae). There areapproximately 100 species of Solidago plants found in North America,most of which are geographically located in the East. Goldenrods areperennial plants that commonly grow along streambanks, ditches,roadsides and other areas where the soil is moist and rich.

The new cultivar was originated from a cross made in a controlledbreeding program in Mishmar Hashiva, Israel. The female parent is aSolidago cultivar designated Y-232 (unpatented). The male parent is anunknown Solidago cultivar (unpatented). ‘Dansosolo’ was discovered andselected by the inventor, Gabriel Danziger, as a flowering plant withinthe progeny of the stated cross in a controlled environment in MishmarHashiva, Israel.

Asexual reproduction of the new cultivar by leaf-cutting was firstperformed by the inventor at Mishmar Hashiva, Israel and hasdemonstrated that the combination of characteristics as herein disclosedfor the new cultivar are firmly fixed and retained through successivegenerations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe basic characteristics of ‘Dansosolo’ which in combination distinguishthis Solidago as a new and distinct cultivar:

1. Small flowers;

2. Rapid growth rate and growth cycle; and

3. Flowers primarily arranged on the top trimester of the stem.

‘Dansosolo’ has not been observed under all possible environmentalconditions. The phenotype of the new cultivar may vary significantlywith variations in environment such as temperature, light intensity, anddaylength without any change in the genotype of the plant. The followingobservations, measurements and values describe the new cultivar as grownin Mishmar Hashiva, Israel under conditions which closely approximatethose generally used in commercial practice.

During the summer and in spring, the plant is grown outdoors in the soilon lifted beddings, and in winter from November to March, it istransferred to a greenhouse where it is grown in the soil on liftedbeddings. The optimal temperature for growing ‘Dansogold’ is 15° C. to25° C. Once it has been established, the plant can be pinched. Pinchingis done at the point when the main stem has reached 5 to 10 cm, or when2 segments are observed on the stem. Not less than a total of 16 hoursof daylight is given, with additional lighting given according to theseason.

Of the many commerical cultivars known to the present inventor, the mostsimilar in comparison to ‘Dansosolo’ is the well-known Solidago cultivar‘Tara’ (unpatented). In comparison to ‘Tara’, ‘Dansosolo’ has a similargrowth habit, but the flowers of ‘Dansosolo’ are brighter in color andmore numerous in number than flowers of ‘Tara’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic illustration shows a typical ‘Dansosolo’plant following growth under appropriate growing conditions, with colorsbeing as true as possible with illustrations of this type. The age of‘Dansosolo’ when photographed is 3 months from the date of planting. Thephotographed plant grew in the soil in a greenhouse on lifted beddings.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe the newcultivar as grown in Mishmar Hashiva, Israel, under conditions whichclosely approximate those generally used in commercial practice. Duringthe summer and in spring, the plant is grown outdoors in the soil onlifted beddings, and in winter from November to March, it is transferredto a greenhouse where it is grown in the soil on lifted beddings. Theoptimal temperature for growing ‘Dansogold’ is 15° C. to 25° C. Theplant can be pinched once it has been established. Pinching is done atthe point when the main stem has reached 5 to 10 cm, or when 2 segmentsare observed on the stem. Additional lighting is given according to theseason and is given not less than a total of 16 hours of daylight. Colorreferences are made to The Royal Horticultural Society Colour Chart(R.H.S.), except where general colors of ordinary significance are used.Color values were taken under daylight conditions in the morning inMishmar Hashiva, Israel.
